Hello,

My Ink datas are originally stored in a relational database. Via so-called
R3-Framework(have to) as client I transform the ink data into a XML file
which looks like:

<Ink>
<Stroke><p x=.., y=.., f=..,t=.. /></Stroke>
<Stroke>...</Stroke>
.....
</Ink>

Then R3 connects the Handwriting Recoginition Server and transfers the data
to it as String Type for analyzing. That works well with returned recognized
text and alternatives. But a problem occurs when I try to use InkDivider to
distinguish texts from graphics. It seems It cannot correctly do this
separation. For example, My first ink data has 18 strokes which should be
recognized to "TEST TEST", but after running with following code included,
it tells there are 18 division units.

//rc is the RecognizerContext
Divider divider = new Divider(rc.Strokes, rc);
DivisionResult divResult = divider.Divide();
DivisionUnits units =
divResult.ResultByType(InkDivisionType.Drawing);
Console.WriteLine(divUnits.Count);

I don't know how to deal with this. Could the String type of ink data be a
possible reason? If the Divider can't separate text from graphics in this
case, is there any other solution? Any help will be very appreciated!

Joe

A bit more explanation on my question:

If I have understood it correctly, for a text handwriting, after calling
"DivisionUnits units = divResult.ResultByType(InkDivisionType.Drawing)",
"units" should own "0" element; and for a drawing, "units" will have some
elements, is that right? But it doesn't work in my application, I don't know
why.

Hey Joe, while I don't necessarily have an answer for you about Divider (I
haven't used it recently) I can tell you that InkAnalyzer is the way to go.
It has far better recognition accuracy than divider, it can create trees of
linked nodes (for example, a circle around a word is analyzed as an
enclosure that has a link back to the word it encloses), and it has a much
simpler object model for working with recognized ink by combining the
analysis (division) and recognition steps into one.

Now of course none of the ink api's are necessarily designed to work on a
server, so keep that in mind. But as for Divider, you might try setting a
RecognizerGuide because I think I recall that has some impact on how it
determines drawings from writing. Drawings are about the height of two lines
of writing I believe.

Hi Josh,

that' a good answer. I'm now working on the InkAnalyzer, thank you!

Joe

Hi,

I have tried to apply InkAnalyzer on my ink data, but failed. I have tried
everything I can. It always returned e.g. "other other other straight other
other ....". If I scaled down the ink size(since it may be too large), it
returns nothing.

I post part of my code here, please help me!

//strokes for each ink data
Strokes strokes = rec.getStrokesFromXML(line);

InkAnalyzer analyzer = new InkAnalyzer(strokes.Ink, gui);
analyzer.AddStroke(strokes);
analyzer.Analyze();

MessageBox.Show(analyzer.GetRecognizedString());

************************************
//I have also tried folgende code, but it gave me nothing back

CustomRecognizerNode customRecognizer =
analyzer.CreateCustomRecognizer(System.Guid.NewGui d());
analyzer.AddStrokesToCustomRecognizer(strokes, customRecognizer);
analyzer.Analyze();

MessageBox.Show(customRecognizer.GetRecognizedStri ng());


Joe

Sounds like it's recognizing the strokes as drawings.

Here's the thing, without a guide, the recognizer uses some standard
defaults for writing size when determining whether or not to classify a
stroke as drawing or writing. You can force it using the
InkAnalyzer.SetStrokesType() method.

Download my Ink Analyzer Explorer to get a better feel for how IA works and
how the various options can influence how it recognizes ink.

Yep, just as you said It seems It tries to recognize any ink as a
shape(circle,squar,triangle...), if I call the
SetStrokesType(StrokeType.Writing), it returns nothing.

I tried to draw fresh ink with following code, it also could only recognize
shapes,any words I wrote were recognized to be "other". It's weird.

BTW, the InKAnalyzer Explore cannot be downloaded,it said "missing required
file".

Ahh sorry I should have mentioned, stupid ClickOnce doesn't work with
FireFox so you have to install it using IE. From that point on it will work
on its own though.

ok, I got it.

but it's weird! Now in the Ink Analyzer Explore I got the same problem,
only shapes can be recognized, and text is recognized to be "other". It
seems the InkAnalyzer installed on my System doesn't support text
recognition, since only when the "Drawing" atrribute in the "Bounds" menu is
chosen, it works. When other attributes like paragraps,line, word were
chosen, there is no response to anything(including drawing) I wrote in the
drawing surface, and "RecognizedString" is other other....

Do you have any idea about this?

The problem is solved. I reinstalled the recognizer Pack. It works.

It doesn't work agin, I'm really fed up!!!

That's very strange. Did you try changing the language (forcing it to
english) or classifying the strokes as text?

Since it started working after reinstalling the recognizers I guess it's not
something simple like you're just writing too big. Sounds like something is
pretty messed up. You're on XP I presume? Vista already has the recognizers
and you shouldn't install the recognizer pack on that OS.
